Title: Holding device
Inventor: NIWA HIDEO
IPC: B25J15/08
Filed: 1989-01-20
Abstract: PURPOSE:To prevent a work piece W from being damaged owing to its side slip by grasping the work piece in place even the work piece is omnipresent with respect to the middle point between the two arms of a holding device in the work piece holding device provided for a carrier. CONSTITUTION:A work piece W is rested on a table, and a holding device is in a condition that both arms 2 are released by means of a release means 4. Under this condition, a carrier is moved until clamps 14 come up to the both sides of a work piece W. Then, when magnetic poles 20 and 21 are magnetized with coils 24 energized, magnetic flux phi is developed in a stationary iron core 17 and movable iron cores 25. The development of the magnetic flux forces the iron cores 25 to be attracted toward spaces 22, the both arms 2 thereby come close together so that each clamping piece 14 of the arms 2 independently comes mutually close to the work piece W in order to let the work piece W be held. In this case, the work piece W can be held even if the work piece W is omnipresent apart from a center point thereof. Following which, the work piece W is lifted up by the holding device.

Abstract: PURPOSE:To prevent the generation of the striking sound of a one-way clutch at the time of speed change in the case of the up-shift speed change between speed change stages in which the one-way clutch is operating, by engaging a clutch which is placed in parallel to the one-way clutch at the time of power off. CONSTITUTION:When the start of a defined up-shift speed change is detected by an up-shift judging means while detecting a power-off condition by a judging means from the rotation speed ratio of input/output shafts calculated by an operating means, a solenoid is turned on by a solenoid driving means, to engage a second clutch provided in parallel to a one-way clutch via a hydraulic selector valve. Thereby, a similar condition to the engagement of the one-way clutch can be obtained, without causing the one-way clutch to be in an engaged condition from a free condition even if the operating direction of torque is reversed midway in the course of speed change. Thereby, the generation of the striking sound of the one-way clutch can be prevented.

IPC: H03H3/02
Filed: 1979-02-07
Abstract: PURPOSE:To realize the manufacture of the perfect side surface electrode via the mask for the miniature etching crystal tuning fork. CONSTITUTION:Mask 10 is attached to crystal tuning fork 7 which is pulled out in many units in alignment from a sheet of the crystal wafer through the etching method along with main surface electrode 3 formed through evaporation or other methods.
